Hazardous waste rotary kiln incinerator is composed of kiln shell, transmission device, support device, retaining wheel device, kiln head sealing device, kiln tail sealing device, kiln hood, etc., and is widely used for its super adaptability to materials For the incineration treatment of hazardous waste, cooperate with the front-end material crushing and conveying (SMP) system to crush, mix and mix all kinds of solid and liquid hazardous waste, and transport them in a sealed manner. Through high-temperature incineration, the organic components in the material are fully oxidized and decomposed at high temperature. The exhaust system is equipped with targeted treatment devices to achieve an emission state that fully meets the requirements of the national standard.

The hazardous waste rotary kiln incinerator incineration system consists of a rotary kiln and a secondary combustion chamber to ensure complete combustion of waste. The rotary kiln itself is used to boil and oxidize the combustibles in the waste, and the inert solid in the waste moves to the other end with the rotation of the kiln body, and then is discharged from the bottom. The boiled steam and combustion gas pass through the back end of the rotary kiln and enter the secondary combustion chamber for oxidation at high temperature. The secondary air is supplied by a blower to increase the air/fuel ratio and the degree of turbulence. Both the rotary kiln and the secondary combustion chamber are equipped with auxiliary burners to maintain a stable temperature in the furnace. At the same time, there are waste liquid nozzles at the kiln head of the rotary kiln and the second combustion chamber, through which liquid hazardous waste can be sprayed into the device for incineration.

According to the characteristics of the waste, the rotary kiln combined incineration equipment is the first choice. It is a waste treatment furnace type recommended by the Ministry of Industry and Environmental Protection. It is suitable for the disposal of solid, liquid, colloid and other hazardous waste, especially used in hazardous waste and chemical solid waste and residue. , Sludge incineration occupies 80% of the market.

The rotary kiln is a horizontal cylinder, which is lined with corrosion-resistant and high-temperature-resistant refractory materials. It is placed horizontally with a slight inclination. The overall rotation of the furnace body achieves uniform mixing and moves to the discharge end along the inclination angle. The combustion rate of solid waste in this rotary incineration method will greatly exceed that of the traditional reciprocating grate structure, and it operates stably and has low breakdowns. The incinerator adopts the flue gas forward design, so that the entire furnace is divided into several stages such as drying, pyrolysis, and oxidative incineration, which is conducive to promoting the mixing and contact of flue gas and waste, and increasing its combustion efficiency.

The rotary kiln incinerator has mature technology, simple and flexible operation, and is suitable for processing solid wastes of various shapes, and can also process hazardous wastes with low melting points. The gas turbulence in the kiln is high, the gas and solid contact are good, there are no moving mechanical components in the kiln, and the maintenance is easy.
